Larus armenicus adult, 18 August 2010, Maagan Michael, Israel. Picture: Amir Ben Dov.
Adult in active complete moult. P3 fully grown, P4 at 2/3 of the final length (and it shows sub-terminal black on both webs), P5-P6 missing, P7-P10 still old (score P3/P7). Note much markings on the bill. Mirror on P9 and on P10.
Primary moult in the inner primaries complete, which commonly goes hand-in-hand with extensive moult in the wing-coverts. Here: the median coverts are regrowing and the central and outer greater coverts are dropped. This exposes much of the secondaries, and in fact you can even see the white bases of the feathers.
